In my records, I call this longiaristata form b, because it's the second form I obtained under that name. I received the seeds of this beautiful little flower from Cameron and Rhoda McMaster in South Africa:
It took seven years for this species to go from seed to flower. That's unusually long for Moraea, and I don't know if it was due to the plants or to my cultural practices. I started them in pots and then moved them to a raised bed.
One individual finally bloomed in May of 2019, later than almost every other Moraea in my collection. It's a small flower, under an inch across (about 2 cm). But its intricate markings make it worthwhile. Here are a few other views:
If you look closely at the center of the photos above you can see the long straight inner tepals that are a key identifier for this species (they're the little white strips in the middle of the flower that look like a shepherd's crook). Keep those in mind because they relate to the story that follows.
Now for the mystery, which I grow as longiaristata form a. Below you'll see photos of some white flowers with a varying number of blue spots on them. I received them from a friend, who grew them as M. longiaristata. He's a very careful grower, so I am sure he received them under this name. But when they bloomed I puzzled over their identification, because according to the books, M. longiaristata is supposed to have the single, straight inner tepal you see in the photos above. The ones I received have an inner tepal with three points on it, the middle one curled. That may sound like a minor distinction, but the biologists use the inner tepal as an identifier for many species.
For comparison, you can see some verified photos of M. longiaristata here.
I thought these might be M. unguiculata, which has a curled inner tepal. I posted some of the photos below to iSpot, a site that was dedicated to nature observation in South Africa (the equivalent today is iNaturalist). The answer I got from the Moraea experts there is that this might actually be M. longiaristata, but could also be M. algoensis, or a hybrid between the two species.
For my own records, I'm going to leave it marked as "M. longiaristata?" because I trust the grower who gave it to me. But I am being careful not to mix it with the species.
By the way, if you have any ideas on its identification, please post a comment.
This individual has relatively few spots...
To me, the flower below looks a bit like pictures of M. tricuspidata, but it's a very small plant and doesn't bloom late enough in the season.
This one has a lot of spots...
As you can see, these are very small plants.
Here's that three-lobed, curved inner tepal.
Whatever its identification, this is a cute little thing, and it's the parent of some hybrids that have a ton of spots on them.
